Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional air-conditioning devices fail to effectively manage thermal stress in indoor environments by not considering individual behavioral patterns and environmental adaptations, leading to discomfort and inefficient energy use.
Innovation Solution
An air-conditioning device equipped with an information acquisition unit to gather environmental and biological data, and a control unit that sets a target human body exergy consumption rate based on the user's behavioral patterns and past environmental experiences, adjusting indoor conditions to minimize thermal stress.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional air-conditioning devices control temperature based on standard thermal environment parameters, then the basic air-conditioning function is provided, but individual thermal comfort and thermal stress management are insufficient
Solution Approach 1:
The system performs preliminary actions by acquiring and storing environmental information and biological data before actual air-conditioning control. The control unit grasps habitual behavior patterns in advance and sets target values for thermal environment indices based on these pre-acquired data, enabling personalized comfort control without increasing operational complexity
Solution Approach 2:
The air-conditioning device serves itself by automatically acquiring environmental and biological data, grasping behavioral patterns, and adjusting temperature settings without requiring manual user input. The system autonomously manages thermal stress by integrating multiple data sources and making control decisions based on grasped behavior patterns
2Object-affected harmful factors
If air-conditioning devices use fixed temperature settings, then energy consumption is reduced, but thermal comfort and thermal stress management deteriorate
Solution Approach 1:
The system changes the control parameter from fixed temperature settings to dynamic target values of thermal environment indices. These target values are adjusted based on acquired biological data and grasped behavioral patterns, allowing the system to optimize thermal comfort and reduce thermal stress while managing energy consumption effectively
Solution Approach 2:
The system incorporates feedback mechanisms by continuously acquiring environmental information and biological data, comparing actual thermal environment conditions with target values derived from behavioral patterns, and adjusting air-conditioning operations to minimize thermal stress on the human body
3Ease of operation
If air-conditioning devices ignore individual behavioral patterns, then system simplicity is maintained, but thermal comfort and personalized environment control are compromised
Solution Approach 1:
The system merges multiple data acquisition functions (environmental sensors, biological data collection) and processing operations into an integrated control unit. This unified approach handles both environmental monitoring and behavioral pattern analysis together, reducing operational complexity while enabling personalized comfort control through combined data processing
Data Source
AI summary
An air-conditioning device includes: an information acquisition unit configured to acquire first information indicating environmental information on an environment in which a target person has been placed in a past or biological information of the target person; and a control unit configured to grasp a habitual behavior pattern of the target person in the first information. A target value of a first index, which is an index related to a thermal environment, is set based on the first information acquired by the information acquisition unit and the grasped behavior pattern.
